I claim 1. A combination blade and pin beater for cleaning cotton or other fibers including a plurality of rotatable arms, a blade mounted at the forward edge of each of said arms and a plurality of pins rearwardly of each of said blades, the outer surface of the blade being located beyond the inner ends of the pins.

2. A combination blade and pin beater for cleaning cotton or other fibers including a plurality of rotatable arms, a blade carried at the forward edge of said arms, a plate also carried by said arms, and a plurality of pins projecting from the plate and located rearwardly of said blade, the outer surface of the blade being located beyond the inner ends of the pins.

3. A combination blade and pin beater for cleaning and opening cotton including a plurality of rotatable arms, a plurality of pins supported by said arms and a cotton deflecting blade in advance of said pins, the outer surface of the blade being located beyond the inner ends of the pins.

4, A combination blade and pin beater for cleaning and opening cotton including a rotatable arm, a plate mounted on said arm, a plurality of rows of pins carried by and pro jecting from said plate and a blade mounted forwardly of the first row of said pins whereby to deflect the fibers to be cleaned immediately prior to subjecting them to the comb ing action of said pins, the outer surface of the blade being located beyond the inner ends of the pins.
